looking for some knowledge
i just swapped most of everything from a 93 dx to a 92 dx shell i had purchased.

i got everything working except the brakes. i have bled them numerous times but still have no brakes. i have great brake pressure until i start the car and it all goes away. the idle goes way up when i press the pedal but still no pressure or braking. i assume its a vacuum issue but im not sure where and how to troubleshoot it from here. brake pros help!! i do have integra rears for the discs.

 

And the slave isnt bad? Did you happen to install any check valves in the line that goes on intake manifold to brake booster?

 

It could be the valve from the brake booster to the intake manifold is backward
